Mandi shares her frozen dessert with her sister. "Wow!" says her sister, "What type of ice-cream is this?" Mandi explains that, because it does not contain any dairy, the dessert is a sorbet and not an ice-cream. Mandi's use of the technical definition

A) using a prototype.
B) rule-based categorization.
C) using a heuristic.
D) linguistic relativity.
